(GRANTED sim an THE PROVISIONS OF THE ACT-01E Manon-e, 1921, 41 s'rar. I.., 1313.

To all whom it may concem:

Be it known that I, GUsT v KRAorIT, a subject of the German Emperor, and resident of Solingen, Germany, have invented certain new and useful Improvements in Tin-Openers, of which the following is a specification. I

This invention relates to an improved tinopener with means for drawing the cutting blade of the same, when driven into the cover of the tin to be opened, firmly toward the edge of the cover during its cutting action in such a way that the sharp cutting edge of the tin isturned down, whereby a neat cutting-out of the cover is effected.

The accompanying drawing shows the im proved tin-opener.

Figures 1 and 2 are respectively a plan View and side view of the same in its position of rest, while Fi 3 is a plan view of the same in its position of use, showinghow the tin-opener is applied to the tin to be opened.

The fork-shaped end of a handle a. carries on a pivot b an arm 0, which at its free end is fitted with the downwardly projecting thus prevented from being damaged or from cutting blade 03. Further, the handle carries on its pivot-end a stationary toothed wheel 6, which serves as a-butt-bearing, in a way known in the art,

If the tin-opener isnot in use, the arm 0 is continuously pressed toward the handle by a torsion spring f or the like, so that its cut ting blade, as shown in Fig. 2, is placed between the forkedmembers of the handle and damaging a person intending, to use the same.

For intended use of the tin-opener, the arm 0 1s, by means of a button 9 arranged thereon for this purpose, turned in the di- 'rection of the arrow (Fig. 1) so far away from the handle that, by a blow or pressure -on said button, the cutting-blade can be driven into the cover of the tin to be opened, the toothed wheel 6 bearing then against the side wall of the tin (Fig. 3). Upon the handle being moved to and fro in ratchetlike manner, thelever action ofsame causes during the active stroke of the handle the cutting blade to be firmly drawn toward the edge of the cover, so that the latter is cut open close to its edge. As the handle acts like a lever, cutting is effected with a very small expenditure of power.

I claim:

In a tin-opener, the combination of a forked handle, having a butt-bearing, an armpivoted to sand handle, a cutting blade carried by said arm, a spring to turn-said blade into the forked handle when not in;
